IMPItOVEMENT IN TH-R-ASHJ'NG-MAG-HIN-ES:

Specification forming part of Letters Patent No.925650, dated lluly'13,,18fi9. I

To all whom it may concern:

Be it known that we, CLEMENT RUssELL, THOMAS H. RUssELL, and WILLIAM K.MIL- LER, of Massillon, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Thrashing-Machines; andwe do hereby declare the following to be a full, clear, andexactdescription of the same, reference beinghad to the accompanyingdrawings, making a part of this specification, in which- Figure 1represents a perspective View from one side of the machine. Fig, 2represents a perspective view from the opposite side, and Fig. 3represents a vertical longitudinal section thereof.

Similar letters of reference, where they occur in the separate figures,denote like parts of the machine in all of the drawings.

Our invention relates, first, to certain mechanism for raising andlowering, and thus adjusting and holding, the concave under thethrashing-cylinder; and, secondly, it relates to the shielding of thegears, to protect them from the dust and grit, as well as to protect theattendants from accidents therefrom 5 and, finally, it relates to whatis termed a threehitch arrangement, in combination with thegear-supports, as will be hereinafter explained.

To enable others skilled in the art to make and use our invention, wewill proceed to describe the same, with reference to the drawmgs.

Arepresents the mainframe of the machine, on which is supportedathrough-shaft, a, which has upon one of its ends a large cogged gear,

B, that is incased, face and rim, by a cover, 0, and upon the end ofthis through-shaft (it,

beyond the gear B and its cover, there is a.

half-couplin g, b, which is protected by a cover, 0, that is hinged tothe case 0 at d, or it may i be fixed rigidly thereto, if preferred, sothat it will protect the coupling from dust and grit, and protect theworkmen.

The gear-wheel B works into a pinion on the shaft or journal 0 of thethrashing-cylinder D, to run said cylinder; and this pinion is coveredby a shield or cover, f, which, for the convenience of getting at saidpinion, may be hinged.

The journal bearings or boxes 9 g in which the shaft or cylinderjournals run are supported on curved arms or brackets E, which extendoutward from the main frame, to bring said bearings outside of thegears.

On the end of the shaft at opposite to that on which the gear B isplaced, or on the opposite side of the machine from said gear, there isplaced a bevel-gear, which is incased in a cover or shield, F; and intothis bevelgear there works another bevel-gear, G, also incased, as at h,said latter bevel-gear being on the end of a shaft, 1;, supported inoutside bearingsjj, as seen in Fig. 2.

The half-couplin g 12 makes one point at which the power to drive thethrasher may be applied.

The shaft 00 extends beyond the bevel-wheel it carries, as seen in Fig.2, and is squared, so that the power may be applied at that end of theshaft, instead of the other end. I

And, third, the shaft '6 is similarly squared, so that the power may beapplied to it.

There are, therefore, three. points to which the power that drives thethrashing-machine maybe applied, from which fact the machine is termed athree-hitch machine.

The object and advantage in the threehitch machine are this: That inthrashing in the field, which is the usual way, the machine is so set orplaced as to throw the straw and chafl' with the wind. If the wind blowsagainst the machine, or against the free exit of the straw and chaff,the grain will not be thoroughly separated or cleaned. As the wind maychange its direction at any time during the operation of thrashing,-thethrashing-machine can be turned in a few moments time to suit thedirection of the wind, whiletochange the horse-power that drives itwould be quite a laborious task. The three-hitch arrangement enables thethrasher to be turned and driven to suit the direction of the wind.

The concave m is pivoted to the frame at n,- and the front of theconcaveis raised, lowered. adjusted, and held by a rack-lever, 0, arranged uponone end of a shaft, 1, said lever and. shaft being held in any desiredposition by a pawl or dog, 8, which takes into the rack or ratchet onsaid lever o, and there holds it in its set or adjusted position.

Upon the shaft 1' there are two cam-arms,1, which project into recesses2 in the concave .or its ram a t e ising .0 owe ing oih points eftheseOQAIPQIIDS 1 'raisessor lowers the frontend of the concave, where it isheld by the dog 8, as above stated.

The other portions of the thrasher not specially referred to in thisspecification are constrncted and operate in the usual well-known way,and, being distinctly shownin the drawin gs, further description of themis not deemed necessary.

Having thus fully described our invention, 1i

what we claim therein as new and desire to secure by Letters Patent,is-- 1. The combination'of the ratchet-lever and dog with the shaft andcam-arms, Working in .egnne t q fl i the nged on v for ai ing, lowe ing,a j s en i s e i cay efsiibstantially as described.

2. The shield or cover a, for shielding the joint in the coupling-rod,as set forth.

3. The three hitching-points b, a, and i, in combination ith the;driving-gear, arranged and snpported substantially as herein describedand represented.
